The "parallel" viewing method may actually require eye directions that are slightly outside parallel. If your intraocular separation is not as large as the separation between the images on the screen, you'll run into problems with divergence. Unless you are a lizard, or you've had a stroke, your brain will fight very hard to avoid divergent eye directions.

      You hit upon two very salient truths about the Huygens probe. The main imaging instrument on Huygens is the Descent Imager Spectral Radiometer (DISR). It contains only a single CCD. The various lens assemblies are connected to the main CCD by a series of optical fibers, each shines light on a different region of the CCD. The CCD is 512x520 pixels though about half of that is reserved as a storage section, the left over 256x520 pixel area is used for the imagers and spectrometers. The visual imagers of the DISR intrument are the High Resolution Imager (HRI), Medium Resolution Imager (MRI) and the Side Looking Imager (SLI). There's also two spectrometers, the Upward-Looking Visual Spectrometers (ULVS) and the Downward-Looking Visual Spectrometer (DLVS). Finally there's space reserves for the Solar Aureole camera which is used to measure sunlight streaming through the atmosphere to determine the size of particles within it.

      The HRI is 160x254, the MRI is 176x254, and the SLI is 128x254 pixels each. Larger images have to be assembled as mosaics and even these aren't going to be large enough to compete with the megapixel images from the MERs. The Pancams and Navcams on the MERs are 1024x1024 each and have essentially a full range of motion so really nice panoramas are easy to create. The DISR is fixed on Huygen's chassis.

      Bandwidth is also a tremendous issue with Huygens. The Huygens probe only hasd a 4800bps datalink to Cassini and has to transmit all of its images within two and a half hours. Even with its limited data rate Huygens was able to transmit 350 images back from Titan which is rather impressive.

      So it is a combination of geometry, bandwidth, and limited technology. Also remember that despite these images being relatively stark in comparison to MER images they contain tons of very valuable information. When researches have had more time to process Huygens images they will get prettier. Until then they're going to remain relatively bland to laymans' eyes but terribly exciting to scientists.

      Crossing (converging) of the eyes induces extra accommodation (an increase of the eye's dioptrical power to bring closer objects into focus), thus blurring the image and (for me anyway) making it much harder to see the stereo image. De-converging your eyes (done simply by imagining a point further away than the monitor... as in staring blankly ahead) allows an unblurred image.

      I think claims based on peoples personal experience rather than on pure fact (such as "divergent stereo is almost impossible") are highly unprofessional, and being a registered Australian optometrist I could use my position to argue that divergent stereo is much easier based on my personal experience, but I wont, as the fact is the ease of di/con-verging the eyes is a variable and as such, some people find it easier to do one and not the other.

      I know many fellow optometrists that find divergent stereo easier, thus I have proved your mother wrong, and hope it serves to make you more cautious before posting assertions that you beleive are "facts".

      As to why the images are poor stereoimages, they are taken from a very large distance. Human stereovision isn't designed to produce accurate 3D of far away objects, but moreso close (at hand) objects. Thus the value of images taken from a long distance as stereoscopic images is dimished.

Driving is a good example: Close things move faster than things farther away, and things grow as you approach them. You learn to infer distances at a very early age.
